Abstract

L'invention porte sur un inducteur intégré variable qui possède une valeur d'inductance pouvant être commutée entre au moins deux valeurs. Dans un mode de réalisation préféré, l'inducteur intégré variable de l'invention comprend un inducteur primaire à plusieurs boucles qui est couplé par électromagnétisme à une paire d'inducteurs secondaires. Les inducteurs secondaires sont reliés entre eux afin de former un circuit fermé dans lequel les inducteurs secondaires possèdent une topologie modifiable que l'on peut commuter entre une connexion en série et une connexion en parallèle afin de modifier la valeur d'inductance sortie par l'inducteur primaire à plusieurs boucles. Dans une application, l'inducteur intégré variable est utilisé dans un oscillateur commandé en tension ("voltage controlled oscillator" ou VCO) du type qui peut être utilisé dans un émetteur-récepteur radio RF multibandes (p.ex., un dispositif de communication sans fil). Dans d'autres applications, l'inducteur intégré variable peut être utilisé dans une charge d'amplificateur syntonisée, un réseau d'accord d'impédance, un oscillateur commandé numériquement ou un quelconque autre type de réseau LC sélectif.
